I recently bought the Phantom 2040 DVD season set and I noticed something off with the video. The picture keeps nudging up and down a tiny bit constantly. I made this handy animated GIF to help illustrate what is happening. Please disregard the lowered image quality due to the .GIF format. The speed of the animation is roughly how quickly this is happening with the actual video.

I hope someone might be able to help me figure out what is happening here and if there might be some reasonably easy way to fix this by transcoding the video anew for myself or something.
